The position of two air outlets and air-out direction thereof affect outbalance to wind pushing performance, and in this embodiment, the first air outlet 41 and the second air outlet 42 are constructed as follows:
Air inducing portion 31 is less than air supplying part 32 bore in the top of air-vent 23 away from bore in the end of air-vent 23, also be, the interior bore of each air outlet rear end is less than the interior bore of its front end, thus, make each air outlet be configured to from air outlet blowout wind towards air supplying part 32.Thus, negative pressuren zone can be formed in front, air inducing portion 31, and utilize negative pressure to be incorporated in air inducing portion 31 by the non-heat exchange wind of outside to mix with heat exchange wind after combing.
And, first air outlet 41 and the second air outlet 42 are preferably formed in the centre position of air-vent 23 and air outlet 11, or closer to the position of air-vent 23, also, two air outlets be preferably formed in the middle part of indoor unit casing inside or middle part slightly biased after position.Like this, the air inducing portion 31 that can ensure to have sufficient length is that the non-heat exchange wind introduced carries out combing, and the air supplying part 32 that can leave again sufficient length mixes with heat exchange wind for non-heat exchange wind and carries out static pressure recovery, ensures air-supply uniformity and air supplying distance.As preferred embodiment, as shown in Figure 4, along in described through air channel perpendicular on the Z1 direction, axis of air outlet 11, air inducing portion 31 is H away from the end of air-vent 23 and the distance of air supplying part 32 between the top of air-vent 23, also be, length on first air outlet 41 or the second air outlet 42 fore-and-aft direction is H, then air inducing portion 31 is 2-3 times of H along the length H1 on Z1 direction, axis (being also fore-and-aft direction), i.e. H1=(2-3) H, and air supplying part is 3-4.5 times of H along 32 along the length H2 on Z1 direction, axis (being also fore-and-aft direction), i.e. H2=(3-4.5) H.
In addition, air outlet front end, namely also the air-out direction of air supplying part 32 near the top place of air-vent 23 can affect wind pushing performance.In this embodiment, this tangential direction is forming the first angle α 1 along self-induced-air mouth 23 perpendicular to the axis Z1 of air outlet 11 along on air-out direction and in through air channel between the direction of air outlet 11, this angle is acute angle, and its angle number can not be too small also unsuitable excessive, preferably, 25 °≤α 1≤45 °.First angle α 1 is in this angular range, can ensures in through air channel, to form enough strong negative pressure to introduce more non-heat exchange wind, can not wind speed be weakened again, ensure that the wind that air outlet 11 is sent has certain air supplying distance.
For the first fan 51 and the second fan 52, be preferably axial-flow fan.And, first air outlet 41 is formed from air inducing portion 31 away from the end 311(of the air-vent 23 i.e. upper end of the first air outlet 41), with the direction in through air channel 3 dorsad towards the first fan first spiral case 611 that the first air inlet 21 extends, and from the top 321(i.e. lower end of first air outlet 41 of air supplying part 32 near air-vent 23), with the direction in through air channel 3 dorsad towards the first fan second spiral case 612 that the first air inlet 21 extends, the exhaust air flue adopting the first fan 51 of axial-flow fan to be positioned at the first fan first spiral case 611 and the first fan second spiral case 612 to limit.Same, second air outlet 42 is formed from air inducing portion 31 away from the end 312(of the air-vent 23 i.e. upper end of the second air outlet 42), with the direction in through air channel 3 dorsad towards the second fan first spiral case 621 that the second air inlet 22 extends, and from the top 322(i.e. lower end of second air outlet 42 of air supplying part 32 near air-vent 23), with the direction in through air channel 3 dorsad towards the second fan second spiral case 622 that the second air inlet 22 extends, the exhaust air flue adopting the second fan 52 of axial-flow fan to be positioned at the second fan first spiral case 621 and the second fan second spiral case 622 to limit.Wherein, the first spiral case of each fan is also the rear spiral case of axial-flow fan, and the second spiral case is the front spiral case of axial-flow fan.
For ease of processing and control shape, first fan 51, first fan first spiral case 611, first fan second spiral case 612, second fan 52, second fan first spiral case 621 and the second fan second spiral case 622 are independently parts, during assembling, by pedestal 201 and top board 202, each parts are mounted with.And drive the fan electromotor 203 of the first fan 51 and drive the fan electromotor 204 of the second fan 52 to be also fixed on top board, and connect with corresponding fan turns respectively.
And after employing axial-flow fan, the position of two fans preferably meets following structural environment:
